  Predicting the Diastereoselectivity of Rh-Mediated Intramolecular C−H Insertion

  摘要：

  Rhodium-mediated cyclization of the alpha-diazo ester 1 proceeds with high diastereoselectivity, to give the trisubstituted cyclopentane 5. A computational model (ZINDO and Molecular Mechanics) based on our current mechanistic understanding of the reaction is presented. This model correctly predicts the dominant diastereomer from the cyclization of 1 and the eight (Table 2) other alpha-diazo esters studied thus far.

  Highly Diastereoselective Cyclopentane Construction: Enantioselective Synthesis of the Dendrobatid Alkaloid 251F

  摘要：

  We report the first total synthesis, and thus structural confirmation, of the dendrobatid alkaloid 251F (1), based on the retrosynthetic analysis illustrated (1 <-- <-- 4). Key observations in this synthesis are that both the Rh-mediated cyclization of 1 and the anionic cyclization of 2 proceed with excellent diastereoselectivity.
